on behalf of The Atlanta Journal-Constitution. The survey included telephone interviews with a representative sample of 1,012 registered voters living in Georgia. Telephone interviews were conducted by land line (n=612) and cellphone (n=400, including 293 without a land line phone or “cell-only”). Interviewing was conducted from May 5 to May 8.


The sample design was a random digit-dialed sample of cellphone numbers and land-line numbers with a Georgia telephone exchange. This sample design is referred to as a “dual-frame” because it includes cellphones and landlines. Both samples were provided by Survey Sampling Inc.

For the land-line sample, interviewers were asked to speak with the youngest adult male or female currently at home based on a random rotation. If no male/female was available, interviewers asked to speak with the youngest adult of the other gender. For the cell sample, interviews were conducted with the person who answered the phone. Interviewers verified that the person was an adult and in a safe place before administering the survey.

All cooperating respondents from both samples were asked about their voter registration status. Registered voters continued with the full interview. People who said they were not registered to vote were only asked demographic questions for weighting purposes.
